I purchased the Type 300 course computer (with control
head, heading sensor,
rudder position transducer, cables) in late 1997, and replaced everything in Jan 2005 as I was told by the
Raymarine dealer in New Zeland that they were not compatible with the C120 MFD and
radar scanner that I also purchased in January 2005. (I have a feeling that this isn't totally correct). I have kept all of the original
equipment aboard as spares as we were circumnavigating. We have arrived back in USA in April 2012, and we are lightening the boat by disposing of spares that we can now do without. I have an ST-2000 tiller pilot which I can couple to my Hydravane
wind steerer if the main
autopilot quits.
The type 300 course computer was around $1700 new. I would want to get $600 for it plus
shipping at cost. The ST-6000+ control head is $225.
